Key Takeaways: Liquid Elements Only two elements on the periodic table are elements at room temperature. They are mercury a metal and bromine a halogen. Four other elements are liquids slightly warmer than room temperature. They are francium, cesium, gallium, and rubidium all metals. The reason these elements are liquids has to do with how tightly bound their electrons are to the atomic nucleus.

Basically, the atoms don't share their electrons with nearby atoms, so it is easy to separate them from solids into liquids. Which method of separation is used for seperating heavier and lighter components by bowing air? Which among the following pairs is not correctly matched? Which among the following had not been discovered by the time when Mendeleev published his periodic table?

Which among the following is called the 'Fool's Gold'? Which type of chemical reaction is responsible for turning the rocks red or yellowish? Suggested Test Series.

Pure carbon can exist in very different forms. The most common two are diamond and graphite.

The table shows some differences between them. Diamond is the hardest natural substance on Earth, but it is also very brittle and will shatter if hit with a hammer. Graphite is unusual because it is a non-metal that conducts electricity. Non-metals Oxygen, carbon, sulfur and chlorine are examples of non-metal elements. They are: dull not shiny poor conductors of heat and electricity they are insulators weak and brittle they easily break or shatter when solid Most non-metals also have these properties: they have a low density they feel light for their size They are NOT sonorous they do not make a ringing sound when hit Eleven non-metals are gases at room temperature, including oxygen and chlorine.

Reactions of non-metals Non-metals react with oxygen to produce non-metal oxides.
